vision & "frames per second"

[NuclearNed]

Not an Arcadio thread... I promise.

I was on a never-ending flight on a turboprop couple of days ago, and I started thinking about vision. The human eye and/or brain can process only a certain amount of visual motion before it gets overloaded - for lack of a better phrase, we'll call this the human's "frames per second." For example, when looking at the moving prop on a plane, our eye sees only a blur. If we could process more "frames per second," we should be able to clearly see the blade at all times with no blur effect.

So what is more the cause of this effect - the eyes, the brain, or both? Is there any way to increase your ability to process more frames per second (exercise, diet, etc.)?

Probably both. Brain can't process things fast enough (not enough RAM and CPU power), and the eyes can't process enough (not enough VRAM). Probably necessary in order to process other things that are important. That's just my theory.

There are exercises and foods that can help, I just don't know what they are. Race drivers for example have much "faster" eyes than normal in terms of how quickly the can change focus and process visual information - this is mostly experience/training but they do do certain exercises to test and improve it.

Correct me if I'm wrong, but one's peripheral vision should be better able to pick up motion, whereas the center is better with details and colors. It has to do with the distribution of rods and cones in the eye.

I notice that, when at a movie theatre, turning my head and watching from the peripheral reveals much more motion flicker than when looking straight on.

Interesting. Probably useful in dangerous situations to pick up fast motion in periphery.

You've never followed one with your eye? It's a bit taxing, but ceases to be a blur.

You can usually only follow a blade at a time, though. Unless you happen to have a multicore brain (Quad Core, here )

Yeah. I'm thinking physical limitations of corneal muscles and pupil dilation on top of input/ouput speed of neurons to process the information.

I would think, however, that the bottleneck occurs mostly with the limitations of the eye.

Your eyes are bombarded with so much information that they cannot fully process it all, hence the blurring ect.

I'm not sure about that. A car fan looks pretty blurred at 1800rpm, but thats only ~ 30rps (revolutions per second)

You could strobe it and "freeze" the blade at a much higher revolution and make out details on the blade easily using your same eyes.

In addition, it also explains certains difference with other animals. Owls have tremendously more rods, and a thicker and shorter nerve pathway to the brain (I think), hence great night vision.

Hawks have more cones allowing them to see in a "higher resolution" and a wider color spectrum (UV light). So they're able to pick out a mouse in a field from a mile up.

oops...meant to edit, not quote.

Is this the same reason why the spokes on a wheel appears to be rotating backwards?

I read a thing about this awhile back and it basically described the issue as one of bandwidth. The optic nerve has a limited amount of information that it can pass without having to increase its size. You can change the speed (FPS) or quality (color vision) to suit different needs. The article or whatever talked about owls, and how their excellent vision requires optic nerves so large the eye loses the ability to move easily in the socket...which is sort of worked around by having that wonderfully flexible neck.

Also their eyes are more oblong than spherical, which also precludes eye movement but allows for such a wide angle of vision.

My theory is that it's just barely exceeding your eye's FPS limitation and you're actually losing track of each individual spoke, but identifying an earlier spoke in a position slightly preceding the one you lost track of and the start of the next "frame" as the same spoke. The close proximity of the spokes and their positions in each frame lead the world modeling software in your brain to think that you are actually tracking the same spoke but going in the opposite direction from the actual motion.

are we talking High def 1080p resolution or like <480p
